You are pretty much asking everyone to reinvent the wheel, just for you. Do some reading, ask informed questions. This is not what we do here.
I have some questions because iam going to play arms in the future as my 2nd Spec.
I saw that some encounters are better for Fury and others are better for Arms.
So what would you advice where should I play Fury and where is it better for Arms?I guess Fury is only better for: Morchok,Hagara,Ultraxion?
And another question is...If I switch at several encounters should I go to the city and reforge completely?Or is there a balance that is good for both specs?
Would be great if somebody has some good advices for me.
